I recieved my BMW Scanner 1.4.0 from xcar360 today to delete my DRL's, but I also have a "hunting idle" while going into neutral occasionally. I'm going to be replacing some suspects of the cause, but I thought it may be wise to do the EU2 scan while I can.

Is there a specific DIY on the EU2 tune with this scanner? I've seen where it's located but I don't want to screw anything up. I keep seeing posts about flashing adaptations and such, and just want to know exactly how I should go about doing this.
